Sanchez has been missing since November with a hamstring issue and Ozil sat out last weekend's draw at Stoke due to a foot injury - but the pair are expected to start against the Blues.

Mohamed Elneny is still awaiting his Arsenal debut with fellow midfielder Francis Coquelin back in training following a knee injury but will not feature, nor will Danny Welbeck, Santi Cazorla (both knee) or Jack Wilshere (leg).
